More particularly, the present invention relates to anapparatus for distributing carbon dioxide with an advanced function ofadjusting a pressure and a temperature of the carbon dioxide for thegeologic injection of the carbon dioxide, capable of optimizing thepressure and the temperature of the carbon dioxide while monitoring thepressure and the temperature of the carbon dioxide, so that thestability for the geologic injection of the carbon dioxide can beensured.

2. Description of the Related Art

Carbon dioxide (CO₂) storage technologies include an ocean storagetechnology and a mineral carbonation technology in addition to ageologic storage technology.

Among them, the ocean storage technology is to store CO₂ in a gas,liquid, solid, or hydrate state into an ocean or an ocean floor.However, the ocean storage technology is not performed yet due to theworries about the destruction of the ocean ecosystem and the instabilityfor the long-term storage of CO₂.

In addition, the mineral carbonation technology is to store CO₂ in thestate of an insoluble carbonate mineral by allowing the CO₂ to besubject to chemical reaction with metallic oxides such as Ca and Mgmainly. According to the mineral carbonation technology, a great amountof reaction energy may be required and environment pollution may becaused when the carbonate mineral is stored and treated. Accordingly,realizing the mineral carbonation technology is difficult currently.Therefore, until now, the geologic storage technology is regarded as themost effective storage technology of CO₂.

The geologic storage technology is to store CO₂ into a proper geologicformation placed at the depth of about 750 m to about 1000 m from theground (or geologic formation placed on the ocean floor).

Since the CO₂ injected at the depth of about 750 m to about 1000 mexists in a supercritical fluid state, the behavior of the CO₂ is veryslow, and the CO₂ reacts with the fluid around the geologic formation orunder the ground, so that the CO₂ is fixed or melted. To this regard,the geologic storage technology is called a geologic sequestrationtechnology.

According to the geologic storage technology for CO₂, in order toeffectively and stably inject CO₂ by using injection facilities such asa pressure device after stably constructing a long-depth bore hole to ageologic formation for geologic storage having the depth of several Kms,ground facilities for high-pressure injection must be designed andmanaged, and the gas leakage must be prevented. In particular, wheninjecting CO₂, the phase change of CO₂ according to the temperature andthe pressure corresponds to an important management factor.

Therefore, an apparatus for distributing CO₂ by more effectivelyadjusting the temperature and the pressure of CO₂ in the geologicinjection of CO₂ is required.

Hereinafter, the detailed structure of the apparatus for distributingCO₂ with an advanced function of adjusting the pressure and thetemperature of the CO₂ for the geologic injection of the CO₂ accordingto an exemplary embodiment of the present invention will be describedwith reference to FIG. 1.

As shown in FIG. 1, the apparatus for distributing the CO₂ according tothe exemplary embodiment of the present invention includes a manifoldpart 110 including a plurality of branching pipes to receive CO₂ forgeologic injection from a storage tank, a distribution chamber part 120to supply the CO₂, which has been received through the manifold part110, to a underground tubular well through an injection pipe 122connected to the tubular well, a temperature adjusting part 130 toadjust the temperature of the CO₂ introduced into the distributionchamber part 120, and a flow rate and hydraulic pressure adjusting part140 to adjust the flow rate and the hydraulic pressure of CO₂ to beinjected into the underground through the distribution chamber part 120.

Hereinafter, the manifold part 110 will be described.

The manifold part 110 refers to a pipe member to integrally transferstored CO₂ from a plurality of storage tanks T, which are separatelyprovided, into the distribution chamber part 120.

To this end, the manifold part 110 is preferably prepared in form of amanifold in which pipes are branched in a plurality of rows so that thepipes are prevented from interfering with each other. Preferably, thenumber of the pipes arranged in a plurality of rows corresponds to thenumber of the storage tanks T. Therefore, the present invention is notlimited to three pipes.

In other words, the storage tanks T provided at separate places to storeCO₂ have outlets connected to pipes 114, respectively, to effectivelytransfer the CO₂. The manifold part 110 combines distributed CO₂, whichhas been transferred through the pipes 114, in the distribution chamberpart 120.

In addition, preferably, the manifold part 110 further includes a socket112 prepared as an expanded tube at one side of a connection partbetween the manifold part 110 and the pipe 114 connected with eachstorage tank T, so that the manifold part 110 can be convenientlycoupled with the pipe 114.

Hereinafter, the structure of the storage tanks T will be described indetail.

The storage tanks T refers to a container to temporarily store CO₂.Preferably, the storage tanks T include compressive tanks to easilystore a greater amount of CO₂ within a predetermined internal volume.

Preferably, an electric heating device 119 is provided below eachstorage tank T to maintain CO₂ stored in the storage tank T at adesirable temperature. For example, the electric heating device 119 mayinclude an induction heating coil to receive external voltage Vs toprovide a heat generation function.

The stop valve 116 is open and closed to intermittently adjust the flowof an internal fluid. In detail, the stop valve 116 is open and closedto adjust the flow of CO₂ toward the distribution chamber part 120 fromeach storage tank T. In addition, the pressure gauge 118 detects thehydraulic pressure of CO₂ to be supplied to the distribution chamberpart 120 from each storage tank T.

Although the temperature and pressure of CO₂ to be discharged from eachstorage tank T are set to 50° C. and 40 bar according to the presentinvention, the setting temperate and pressure may be selected as aproper value according to the conditions and environment to perform thepresent invention.

Although the CO₂ stored in the storage tanks T flows through the pipes114, which are separately provided, the CO₂ is combined in thedistribution chamber part 120 through the manifold part 112.

The distribution chamber part 120 has an inlet 120 a communicating withan output opening of the manifold part 110 and an outlet 120 b connectedto an injection pipe 122 extending toward the underground tubular well,that is, a bore hole. Accordingly, the distribution chamber part 120supplies CO₂, which has received therein through the manifold part 110,through the injection pipe 122.

In detail, the distribution chamber part 120 serves as a CO₂ distributorto combine CO₂ received from the storage tanks T through the manifoldpart 110 and supply the combined CO₂ to the underground tubular wellthrough the injection pipe 122 provided at an output side of thedistribution chamber part 120.

In order to more stably combine and distribute CO₂, an outer portion ofthe distribution chamber part 120 includes a casing 124 having the formof a pressure container. A heating part 133 serving as a component of atemperature adjuster 130 to be described later may be provided on anouter peripheral portion of the distribution chamber part 120 in such amanner manner that the heating part 133 can be accommodated in thecasing 124. The heating part 133 heats CO₂ contained in the distributionchamber part 120 to increase the temperature of the CO₂ to a temperatureset by a user.

Hereinafter, the temperature adjuster 130 will be described.

The temperature adjuster 130 adjusts the temperature of CO₂ introducedinto the distribution chamber part 120 as described in brief.

To this end, the temperature adjuster 130 may include a temperaturesensor 131 to detect the temperature of CO₂ for geologic injection, aheating part 133 for heating CO₂ introduced into the distributionchamber part 120 to adjust the increase of the temperature of the CO₂,and a controller 135 (see FIG. 2) to perform a comparison operation forthe temperature of CO₂ detected by the temperature sensor 131, calculatea compensation value for the temperature of the CO₂ to be increased, andcontrol the operation of the heating part 133.

The configuration of the controller 135 (see FIG. 2) will be describedin detail later with reference to FIG. 2, and only the configurations ofthe temperature sensor 131 and the heating part 133 will be described indetail in the following description.

The temperature sensor 131 is mounted on the injection pipe 122, whichis connected to the outlet 120 b of the distribution chamber part 120and extends toward the underground tubular well, and is a sensing deviceto measure a real temperature of CO₂ supplied to the underground tubularwell. As examples of the temperature sensor 131, various types ofthermometers may be used.

In addition, the heating part 133 surrounds the outer peripheral portionof the distribution chamber part 120 as described above in brief in thedescription about the distribution chamber part 120.

The heating part 133 heats CO₂ introduced into the distribution chamberpart 120 within the predetermined temperature range. According to thepresent embodiment, CO₂ may be maintained at the temperature of about50° C. Such a temperature condition does not restrict the presentinvention.

As an example, the heating part 133 may include an inductor heat toincrease the temperature of the CO₂ contained in the distributionchamber part 120 by generating resistance heat after receiving externalvoltage Vs. The present invention is not limited thereto, but mayinclude various forms of heating part according to various embodiments.

The temperature adjuster 130 may be described in more detail withreference to FIG. 2. Referring to FIG. 2, the temperature adjuster 130includes the controller 135. The controller 135 actively controls thetemperature sensor 131 and the heating part 133 such that the CO₂temperature detection by the temperature sensor 131 can be incorporatedwith the operation of the heating part 133.

In other words, the controller 135 which serves as an additionalcomponent of the temperature adjuster 130 includes a temperaturecomparison part 136 to compare the temperature of CO₂ detected in thetemperature sensor 131 with a preset reference value, a temperaturecalculator 137 to calculate a compensation value for the temperature ofthe CO₂ to be increased by the heating part 133 through the comparisonbetween the reference value and the detected CO₂ temperature, and atemperature controller 138 to control the operation of the heating part133 so that the temperature of the CO₂ contained in the distributionchamber part 120 is increased by the compensation value.

In this case, the preset reference value refers to a temperature valueof CO₂ to be injected into the underground tubular well, which is presetby a user. If the temperature of CO₂ detected in the temperature sensor131 is lower than the reference value, the temperature of the CO₂ isincreased by the compensation value corresponding to the differencebetween the detected CO₂ temperature and the reference value bycontrolling the operation of the heating part 133.

The controller 135 further includes the temperature comparison part 136,the temperature calculator 137, and the temperature controller 138, sothat the temperature adjusting function according to the presentinvention will be more actively controlled.

Hereinafter, the flow rate and hydraulic pressure adjusting part 140will be described with reference to FIG. 1 again.

The flow rate and hydraulic pressure adjusting part 140 adjusts the flowrate and hydraulic pressure of CO₂ for geologic injection through thedistribution chamber part 120.

As shown in FIG. 1, the flow rate detector 141 and the hydraulicpressure detector 143 are provided on the injection pipe 122 toeffectively detect the flow rate and the hydraulic pressure of CO₂flowing out of the distribution chamber 120. The arrangement of the flowrate detector 141 and the hydraulic pressure detector 143 is only oneexemplary embodiment, but the present invention is not limited thereto.Therefore, according to other embodiments, the flow rate detector 141and the hydraulic pressure detector 143 may have various arrangementforms according to positions, environments, and various conditions forthe present invention.

The flow rate detector 141 refers to a typical flow meter. Accordingly,the flow rate detector 141 may include variously-released common flowmeters. In addition, the hydraulic pressure detector 143 refers to atypical hydraulic gauge. Therefore, the hydraulic pressure detector 143may include also variously-released common hydraulic gauges.Accordingly, the details thereof will be omitted.

In addition, the present invention may include various arrangement formsof the valve parts 145 and 147. In other words, the valve parts 145 and147 shown in FIG. 1 are separately arranged about the flow rate detector141. Differently, the valve parts 145 a, 145 b, and 147 shown in FIG. 2are installed on dual pipes branching from a portion of the injectionpipe 122 according to an arrangement form different from the arrangementform of FIG. 1.

The flow rate and hydraulic pressure adjusting part 140 may furtherinclude a flow rate and hydraulic pressure controller 149 except for theflow rate detector 141, the hydraulic pressure detector 143, and thevalve parts 145 and 147.

The function and the role of the flow rate and hydraulic pressurecontroller 149 can be recognized in detail through FIG. 2.

In other words, the flow rate and hydraulic pressure controller 149compares data about the flow rate and the hydraulic pressure of CO₂detected through the flow rate detector 141 and the hydraulic pressuredetector 143 with the preset reference values and controls the closingand opening of the valve parts 145 a, 145 b, and 147 so that CO₂ to beinjected into the underground is supplied at the proper flow rate andthe proper hydraulic pressure. Although the pressure of CO₂ to beinjected into the underground is preset to about 40 bar, the pressuremay be preset to a different value by a user.

The flow rate and hydraulic pressure controller 149 actively controlsthe flow rate detector 141 and the hydraulic pressure detector 143, andthe valve parts 145 a, 145 b, and 147 closing and opening in cooperationwith the flow rate detector 141 and the hydraulic pressure detector 143,so that CO₂ can be distributed more quickly and exactly.

Hereinafter, a remote monitoring device adaptable for the apparatus fordistributing CO₂ with an advanced function of the pressure andtemperature of the CO₂ for the geologic injection of the CO₂ accordingto the preferred embodiment of the present invention will be describedwith reference to FIGS. 3 and 4.

Referring to FIG. 3, the remote monitoring device is additionallyapplied to the apparatus for distributing CO₂ with an advanced functionof the pressure and temperature of the CO₂ for the geologic injection ofthe CO₂ according to the preferred embodiment of the present invention.

In other words, as shown in FIG. 3, the temperature data, the flow ratedata, and the hydraulic pressure data of C0₂ detected by the temperatureadjusting part 130 and the flow rate and hydraulic pressure adjustingpart 140, and all signals for the operations of the heating part 133 andthe valve parts 145 and 147 according to the data can be transmitted tothe integration server 160 through a communication interface 150 over awire/wireless communication network.

The integration server 160 transmits data, which has been receivedtherein through the communication interface 150, to a remote userterminal such as a user PC 170 or a user smart phone 172, and applies acommand, which has been received from the user through feedback, to thetemperature adjusting part 130 and the flow rate and hydraulic pressurepart 140 through the communication interface.

In addition, the integration server 160 may further include a data logpart (not shown) to record the data received through the communicationinterface 150 in an additional recording medium.

Data transmitted to a remote user through the integration server 160 areconverted into at least one of text information, image information, andvoice information, so that the data can have the form receivable in theuser terminal (such as the user PC 170 or the smart phone 172).Accordingly, remote monitoring and supervising in the process ofdistributing CO₂ can be conveniently performed, and these functions helpsystematic integral management of the CO₂ distribution process.

FIG. 5 is a view showing a case in which the apparatus for distributingCO₂ with an advanced function of the pressure and temperature of the CO₂for the geologic injection of the CO₂ is applied to a bore hole to storethe CO₂.

Referring to FIG. 5, through the apparatus for distributing CO₂according to the present invention, CO₂ stored in the storage tanks T isintegrally combined with each other through the manifold part 110 andthe distribution chamber part 120. Thereafter, the CO₂ is injected intothe tubular well under the ground G in a state that the CO₂ ismaintained at a proper temperature and at a proper pressure according tothe functions of a temperature adjusting part 130 and the flow rate andhydraulic pressure adjusting part 140.
